GEORGE R. YOUNG, 0F EIDGEWOOD, NEW JERSEY.

TIME DAMPER APPARATUS.

To all whom it may concern:

Be it known that I, GEORGE E. YOUNG, a citizen of the United States, and a resident of Ridgewood, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Time Damper Apparatus, of which the following is a specification.

This invention relates to time damper apparatus, and has for its object means by which the draft appurtenances, dampers, valves, or doors of a furnace, heater, boiler, and the like can be both opened and closed, by time releasing apparatus or mechanism.

The organization of the invention is characterized by embodying the double function of both opening and checking, or checking and opening, or either opening or checking independently of each other, the draft of a furnace, heater and the like, by operating in conjunction with time release mechanism, similar to that generally embodied in an ordinary clock, or other time piece.

This invention is an improvement of the invention embodied in my patent, for time damper apparatus #781,170 dated January 31, 1905.

The essential elements of the invention comprise a time piece, release mechanisms, a movable support actuated by one of the release mechanisms, a driving sector to actuate the movable support, and the latter actuated by the other release mechanism. The movable support has means' connected therewith, by which it can be locked in place, independently of the releasing mechanism with which it coacts, and these means primarily distinguish this invention from the invention covered by my Letters Patent #781,170, above cited.

In the drawings, Figure 1 represents an elevation of the invention on a reduced scale, applied to a steam heater, Fig. 2 shows a side view of the frame of the invention, with a bracket for securing it in place, Fig. 3 shows a front view of the main portion of the invention with the dial plate removed, Fig. 4 is a partial back view of Fig. 3, Fig. 5 represents a section of Fig. 4 on the line :12, 00, Fig. 6 shows a partial top view of Fig. 4, and Fig. 7 represents an enlarged view of a small portion of Fig. 5, Fig. 8 shows-an elevation of the driving sector, Fig. 9 is an end view of Fig. 8, Fig. 10 represents an enlarged partial section of Fig. 4 on the line 02, cc, Fig. 11 is a face view of a detail Specification of Letters Patent.

The frame of the invention is shown at A, from which extend the supporting lugs a and guide lugs a, by means of which the said frame can be easily placed on and supported by a bracket B, which latter is fastened to a wall B or other support, with the screws C.

A movable support D is journaled on a pivot A. extending from the frame A. The said support D contains the teeth d, and a movable tooth D journaled on the pivot d, extending from the disk 0Z of the support. The tooth D is counterweighted by its leg (Z extending on the opposite side of the pivot d, so the said tooth can swing about said pivot, its movements being controlled by the collar d at the circumference of the disk 0?, and the boss d -extending from its central portion. In front of the teeth d, extends a circular flange d, from which projects the curved guide 01 for a chain or cord (Z10, that leads to a pulley a3 and then extends to the guide y, of the bell crank Y. A chain (Z extends from the said bell crank, and leads to the front door E of the heater E. A movable lever 3 is journaled on the bell crank Y, the end of the lever carrying a chain y that leads over a pulley y, and connects with the rear damper E The said chain g also connects with one end of the counterweighted lever E of the regulator E and a chain E leads from the opposite end of the lever E to the draft door E. The bell crank Y is fully described in my Patent #781,170.

The flange d of the movable support D carries a latch F which is journaled on a pin f extending from. said flange. The latch has a tooth f, a sustaining end f and a handle f for which latter the curved guide d is cut away. An arm (i with a bearing face (Z and a handle D extend from disk (Z of the movable support, and a stop a projects from the face of the frame A, for the said movable support.

On the frame A is journaled a sustaining lever G on the pivot g. It carries a pin Gr arranged to be engaged or locked with the tooth f of the latch F. The sustaining lever is connected with a spring G which latter is fastened to the frame A and a pin 9 projecting from the said lever G. The free end of the sustaining lever G engages a sliding bar H, between a pair of prongs 7L extending therefrom. The said bar is supported on the back of the frame A on two pins H, the latter engaging a pair of slots 7L2 formed in the bar.

A clock I or other time piece has formed thereon a pair of lugs I with a cross-bar The lugs I fit a pair of supports A formed in the frame A, and the frame is cut away at A to enable the manipulation of the key T to wind the clock. The hour post I of the clock extends on the outside of the casing thereof, and carries a pinion I and a knob 2'.

The pinion I drives a train of gearing that propels the releasing mechanisms of the invention, and comprises the spur gear J carrying the pinions J on the pivot j. The pinion J meshes with the gear J sup ported on the pivot j and on the latter is also carried the gear J A gear J on the pivot j meshes with the gear J, and also with the gears J and J which latter are respectively supported on the axles j and 7' the said axles being capable of rotation in the hearings in the said gears J 6 and J On the axle j is fastened a collar L with a notch L, and a pin L extends from the face of the gear J 6 arranged to engage with the said notch. A collar M with a notch M extends from the axle f, and a pin L extending from the face of the gear J is arranged to engage with the notch M.

A spring N extends from the face of the frame A, straddles the axle j and bears against the face of the spur gear J, tending to move it along the axis of the axle j, away from the face of the said frame A. The spring N has at its end the hooked end 12., which in Figs. at and 5 is shown to bear against the outer face of the sliding bar H, the latter being in its downward position, and enters an opening H in said bar when it has been moved to its upward position, as shown in Figs. 7 and 10. t

On the rear face of the frame A there is journaled an arm K on pins K extending therefrom and supported in the bearings K held in place by a screw K A plunger K extends from the free end of the arm K, which plunger is arranged to pass through an opening in the frame A opposite the hooked end n of the spring N, so as to engage with the latter when the bar H is in its upward position. A spring K tends to maintain the plunger K* in its opening therefor in the said frame A.

A spring 0 similar to the spring N extends from the frame A, straddles the axle j bears against the wheel J to move the latter outwardly along its axis from the frame A. It has a hooked end 0 which is arranged to pass through an opening A in the said frame, and engages a sustaining lever P that is journaled on a pin The boss 7) of the lever P has an opening p (see Fig. 12) to secure a tongue 1' extending from the driving sector R. The latter is journaled on a pivot 2" extending from the frame A, and has the toothed sector 1- It has adjustably clamped thereto the counterweight 1-. frame A, in the path of the driving sector R. A guide Q extends from the frame A for the free end of the sustaining lever P.

On the pivots A and 7" are placed separators S, that support a dial plate T, screws 2, clamping the dial plate in place by passing therethrough, and through the said separators into threaded openings in the said pivots A and 1". At the upper end of the dial plate is formed an opening T with lugs t that hold in place a dial card T for two dials V and V. The axles j and y have each a shoulder formed thereon, which bear against the said dial card to help keep it in place. Beyond the shoulders the said axles extend through the said card. The axle j carries the pointer WV, with the knob TV and the axle carries the pointer V with knob To use the invention, it is customary to arrange the elements to operate the draft appurtenances in one direction at a predetermined time, and in an opposite direction in an interval thereafter. For the purpose of explanation it may be first supposed that the draft is closed, as shown in Fig. 1, and that it is desired to first open the draft, and then to again close it. To open the draft the chain must be lowered, and to then check the draft it must be raised to its present position. To obtain the location and disposition of the elements shown in Fig. l the movable support D must have been turned with its handle D down as shown in Figs. 1 and 3, and its teeth out of mesh with the teeth of the driving sector R. It can be turned to this position by means of the handle D At the same time the tooth f, of latch F is made to bear and lock against the pin G of the sustaining lever G, when the said movable support D will be held in place, and sustain the chain with the weight of the draft appurtenances. The pointer W over the dial V having been set at a predetermined time for releasing the A stop A extendsfrom the/26" movable support D, the clock by means of the pinion I on the hour post I will drive the train of gearing J to J, and at the appointed time the hooked end a, of the spring N, will spring from the opening H of the sliding bar H, and the tooth f bearing against the pin Gr raises the end of the sustaining lever Gr having the pin Gr and lowers the other end which is located between the prongs h of the bar H. As soon as the tooth f is released from the pin G, the movable support D turns to the position shown in Fig. 4, and consequently lowers the chain (Z The position of the movable support is controlled by the stop a against which it then bears. Immediately after the sliding bar H has dropped or has been lowered, the tooth f being disengaged from the pin G it is again pulled up by reason of the spring G pulling up the end of the sustain ing lever G, the end of which latter bears up against one of the prongs on the forked ends lb of the said bar H. When the hooked end a of the spring N is in the opening H its upper portion bears against the lower portion of the plunger K (Fig. 5), and the upper portion of said plunger bears against the inner face of said bar H, so that when the end it moves out of the opening H the bar H is allowed to drop. After the bar H has again been raised automatically by the action of the spring G ,.the plunger K enters the opening H and sustains the said bar in position, the spring G pulling the lever G high enough to allow the entrance of the said plunger K into the opening H and the pin G will then be again in proper position to lock with the tooth f of the latch F. It will be noted that after the upward movement of the bar it is supported on the plunger K. The elements are then again ready for the spring U to actuate, and its first action is to push the plunger K back out of the opening H and allow the bar to rest on its hooked end a. When the train of gearing has actuated the gear J so that pin L comes opposite the notch L, the spring N will snap out of the opening H and allow the bar H to drop.

The next operation of the invention is to again raise and turn the movable support D from the position shown in Fig. 4 to the position shown in Fig. 3, by means of the teeth r of the driving sector R engaging the teeth (Z of the movable support D. The arm d of the movable tooth D now bears against the boss d of the movable support, and raises the said tooth to be in position to be engaged by the teeth r of the driving sector. The driving sector will turnup from the position shown in Fig. 4, when the releasing mechanism connected with the dial V snaps the spring 0 out of engagement with the sustaining lever P, which occurs when the pin L of the gear J 7 enters the notch M of the collar M. When the driving sector and the movable support are both in the position with their teeth upward from the pivots on which they turn, either one can be turned independently of the other, and the movable support can be easily turned by hand, by releasing the same by unlocking it from the latch F. It Will be noted that the movable support can be locked in position any time when the bar H is in its raised position and is supported either by the hooked end of the spring N or on the plunger K The raised position of the bar H brings the pin G in proper position for locking itself with the tooth f.

Should the movable support be placed with its arm (l up, as shown in Fig. l, and if the driving sector is located with its sector up, that is opposite to that shown in Fig. 4, the said sector can easily be lowered on account of the movable tooth D, of the movable support being pushed out of its path, as the teeth of the sector passby the said tooth.

In Figs. 3 and 3 a modified means is shown of holding in position a sustaining lever 1 similar to the lever G by replacing the spring G with a lever 2 with its counterweight 3. The lever 1 is fulcriuned on the pin 4 extending from the frame A, and one end of the lever 2 bears up against a pin 6 on the lever 1.
